[AG-TECH] shared browser with private website possible?

[ivo schindler]

don't you need to hand out passords as well? of course one could
generate sessionpasswords, but it is still to complicated. Compared to
all the proposed solutions it is much less difficult to use microsoft
netmeeting to share secured websites. i think this is a pity and i don't
want to propose netmeeting. it lacks a lot of usefull stuff that AG provides.

maybe an extended pictureviewer, where one could grab the actual screen
and refresh it every second would already almost solve this problem...
it wont be very elegant. but more comfortable than the other solutions
(hardware, vnc, proxy)

is there anything planned for sharing for example a secured website or a
local window for an upcoming release of AG or by some independent developer?

thanx again and greetings.ivo
