To do it through two ISPs would require some serious effort. At least
one of the two connections would need to be tunneled -- say, PPP over
L2TP over UDP over IP over PPP. You'd then need to get that tunneled
connection back to the bundle head on the other ISP. Even if you
could get all of that to work (and the ISPs went along with it), it
would perform like a stuck pig and would have the worst possible
So, the short answer is, "no, you can't do that."

Putting aside the fact that you can run MP on a single link if you
want (which would be helpful on those annoying PPPoE links with MTU of
1492, since MP can give you any IP MTU you like), all you need is
multiple PPP links. So, for instance, if you had two ADSL bridges
using PPPoE going to the same provider, you could run MP between those

(Note that TAs aren't generally used with PPPoE.) Usually, with TAs,
you're talking about a single ISDN line, and you're using MP so that
you can aggregate the two B channels. That doesn't mean you can't
aggregate channels from multiple ISDN lines -- you can. To do it,
though, you need access to the real B channels. If you have TAs with
two serial ports (one for each channel), or if you have integrated
ISDN adapters (where all channels are directly accessible), then you
can do this. In testing, I've run MP links with 30 B channels in a
single bundle over E1 lines.
If the TA has multiple ISDN ports (I know of routers like that, but
not TAs), then the TA can safely do the MP. Otherwise, if multiple
ISDN ports are in use, then the TA can't be doing the MP fragmentation
