It will, possibly, exist two different models for the two schools of thoughts on the subject. The first is the time-independend, space-enabled mode, where the user will face the initial difficulty of self-identification every time the PWM is activated. The second, well, we can not really call it challenge, but rather a property of this particular model is the complete inability of the operator to take any actions, once the vessel has been (even correctly!) identified and taken possession of. The reason for the said properties is the approach of the school of though, that accepts the anchor space-universum, applicable to each consciousness with the consideration of it's past and it's previous decisions and by transferring of the said consciousness to another space-universum the machine merely projects the rendering of the "what if" scenario to the user of the PWM like it would be a film. At this stage the user is robbed of the ability of making any decisions as well as being influenced by it's environment or have any chance of acting or reacting to the changing environment. The proposed name for this model of the Possible World Machine in it's first version is

Йыхскинатор

The other model of he PWM works like an imaginary set of infinite set of railways, each representing  user's consciousness at that specific point in time. At the same time the user's consciousness runs through the time with the constant speed with no possibility of the machine to influence this factor. Each said railway track is either connected with the next one to it with the infinite number of side tracks, length of which always equals zero; or as another experimental model is trying to do, connect each track with all other track by ways of infinite number of connections. However we are still not sure how our colleagues are going to manage the mess, considering that we can not afford missing out the decision opportunity even by the smallest minuscule part of the nano-second, thus even in the experimental model's case the connection still can not be longer than zero. The proposed name for the said model is

Ыксентатор

The Ыксентатор is a very recent model, developed by your's truly. Until then, the Йыхскинатор has been one of the very few models available for the general use during the initial stages in the philosophical community. It also has been the most successful one too, thus the rest is not named in this document and is considered under the generic term of the Possible World Machine.

The development of the Ыксентатор, IMHO, will positively reflect on the Possible World Travel, while, at the same time, diminishing the problem of the space portability, or rather inportability, since each scenario is readjusted real time to the user, rather than the machine physically takes over the conscientiousness and ports it to some other dimension. Instead it merely replaces the current world with the chosen one, so there is no lag in the perpetual experience as an entity in the user of the machine, such as in the case of the Possible World Travel cases mentioned above as problematic.

More to come ... possibly ...
