Thank you to all of you that have helped so far.

I am looking for connecting up to 36 computers to the internet, of
which only 16 are likely to ever be connected.  The possible
connections are currently ADSL (not good enough for gaming due to
contended uplink aswell as downlink), 256k leased line (expensive in
comparison to ADSL) or multiple ISDN connections.

Currently I think that my ideal solution will be to have ADSL
(2mb/256k) for internet (browsing / downloading) users, complemented
by multiple ISDN connections for gamers, particularly for tournaments.
By my reckoning, since each player usually uses 25kbits up/down, this
leaves me with 5 players per ISDN connection.  So 3 ISDN connections
will give me 15-16 players online for gaming.

Q1: How do you connect the ISDN connections together (bonding), I have
heard about bonding routers and the rumour that bonding 2 connections
is cheap enough, but 3 is expensive??  Would anyone know prices
(prefably UK prices) and part numbers for such equipment?  I have
heard of dual bonding 64kx2 ISDN, but I *think* I want 3x128k single
channel ISDN connections.

Q2: Would I need 3 accounts with an ISP, one per ISDN connection?  

Q3: Will the routers automatically release connections when demand
drops?

Q4: When a router picks up / drops will there be any connection issues
(lag in a game) during this time?

Q5: Can I make most of the machines point to the ADSL connection and
only 16 point to the ISDN dynamically (by a firewall or some non-cable
solution)?  This is so I can change which machines are connected to
where without pulling cables?!

Cheers,
Rob.
