This generally includes all faster internet connections that is sold to the average consumer. You would need to triple check with any ISP about Upstream speeds with any connection before you pursued originating streaming multimedia from a subscriber access point. A lot of these constraints are controlled at the ISP or before it is delivered over the final link to the user. You CAN arrange to deliver your multimedia presentation hookup to a server which then would handle the multiple connections. IT will Need a FAST link Possibly equivalent to T3 access of better to handle the distribution of the packets. This way the originating point would only need a single FAST upstream connection. This would of course include a fast downstream speed. Possably only up to the equivalent speed of a T1 line. -- Paul Holmgren Hoosier Corps #33, L-6 2 57 300-C's in Indy
