Yup thats a problem, but there is only a very remote problem of it really
causing serious problems, IMO I would agree with the rest that it is far
cleaner to use the standard URI escaping mechanism, I would have to agree
that it is far better to sort it out now than wait until some later point
down the line, the longer we leave it the worse it is going to be, since we
are now documenting gatewaying properly now its far better to make it the
best we can than having to be too tightly restricted by bad legacy hold
overs. Using standard escaping also gives us the benefit of being able to
represent reliably in clients what ID in the legacy network the JID
represents, e.g. if it is an MSN ID you could show the end user the
user at hotmail.com address along with an MSN icon which is far more user
friendly for novice/new users, and you can do it using a common code base
for all transport types in a nice clean way.

It surely wouldnt be "that" hard for someone to patch MSN-T to support this
