No, you cannot do bonding if you're using multiple ISPs. However, some 
ISPs outside of the US are using ADSL2's bonding feature to do exactly 
what you want. In that case, they use special hardware at their end, and 
give you a special router - and it all just looks like one connection to 
your machine. This may be a good option for you outside of the US.

See this: http://lartc.org/howto/lartc.rpdb.multiple-links.html. It is 
non-trivial; I have yet to find a nice 'end-user' way to enjoy multiple 
ISP connections.
