They might not necessarily put them into their rosters but they do often put 
them into their bookmarks which is an equally problematic place IMO, if not 
moreso as it couldnt be automatically updated like a roster could be when a 
transport is upgraded to use the new escaping method (i.e. it could 
unsubscribe etc from the old contact and resubscribe the new ones the next 
time the user uses it, which is one of the reasons that I fail to see it 
being as much of a problem as some people are making out for MSN transport 
users, or if its been implemented by both sides it becomes even less of a 
problem as roster subsync will deal with it with even less hassle).

I thought that the main stated goal of using # was not breaking anything at 
all, which means we cannot use #, trying to rationalise it as "its fine 
because it wont affect many people" is the same point I made about the MSN 
transport which you seemed to ignore, sorry but this does rather strike me 
as double standards, if we arnt using # for the reason of not breaking 
anything then we really should go along with something more standard like %.

Yea that would seem better to me, at least its using a character that I 
havent really seen used, so it really wont break anything.
