Please if someone could clarify if some sort of adjustment has been made in any occasion for such cases involving long distances (things like avoid purely formal encounters, examinations by videoconference, etc) it would be great.
Studied Liber 185 under this question I´ve found little thing that could carry absolutely necessary physical presence, IMO. Such things described there as the candidate "being received" by the tutor can pass as simple formalities, in the same way that of the "paying a Guinea" was something sort of symbolic that has been abolished (as I have understood). Same with the "reception" of the robe.
Also, Crowley makes it clear referring to these kind of things (in One Star in Sight) as having purely practical reasons and being flexibles to adaptation, so it´s not clear that these ones in particular could not be adapted when the circumstances requires it.
As for the examinations by videoconference, they are not a strange thing in the academic world today. Special measures for avoiding fraud could be easily made.
In the two first grades I´ve found nothing that could require necessary physical presence, even in examinations (The examination in Journeying on the Spirit Vision could go by videoconference without problem).
The Yoga examinations of the Zelator could more reasonably require direct presence because of some particularities (asana particularities and so on), though it´s not sure that they probably could not be made also by videoconference.
I don´t checked beyond Zelator because these three grades are already no small business.
That would leave the obligatory physical presence for the ceremonies of the Neophyte and Zelator initiations, and probably Zelator examinations in yoga though it´s not sure.
Just some idle thougths about this question, please don´t even take it as "suggestions", even less as a sort of complain. I don´t even know if some kind of similar arrangement is made or has been made for such kind of cases.
