Is it possible to use these together on one PC? If so, how? :)
Any advice appreciated...

Yes, I do. But you will only ever be able to use the last device connected.

ie: Windows will use the last allocated ip address. AFAIK you can't bridge the two connections. (Different protocols?)

eg: I'm on ADSL. I see something I want to download. I connect to 3g. It downloads fast (2 -300kbps). Activity on ADSL pauses. I disconnect from 3g. ADSL takes over (back to 40kbps). There is not simultaneous activity on the two connections in other words.

It should be possible, look up routing. You can add routes for certain traffic to go through ADSL, and certain traffic to go through 3G. Think of it like Local / International split, the exact same principal at work.
 
On a totally unrelated note, just checked out your PC, snap on the Dual PSU fun :)

I imagine this is possible with one of the new dsl /3g routers, like a BiPAC 7402X , but without one of those, how would one do it? Dsl is a fixed line ppoe, and 3g is a dial-up modem. This is all beyond me...:(

Well, I'm not too sure about how this would work on Windows, but I know it's possible. Here's how I'd do it in FreeBSD:

1) Set up /etc/ppp/ppp.conf with both accounts, make sure 'add default HISADDR' is not included, so no default route gets added. (FreeBSD's ppp handles both dial up style ppp and PPPoE)

2) ppp -background -nat adsl; ppp -background -nat 3g

3) route add default adsl

4) route add www.myadsl.co.za -iface tun1 (tun1 would be the 3g connection, since it was started later)

EDIT:
If you are using a normal ADSL modem (lets say 192.168.2.1), this should be rather easy under Windows. All you need to do is connect to the 3G account, and then use the route command ("route /?" for help) to dictate which traffic goes where. You just need to use 192.168.2.1 (for example) as the gateway for the ADSL and whatever the other end of the PPP link is for the 3G
