network question

Hi,
I am moving into a new apartment soon and i am looking into getting 2 seperate internet connections in the apartment. Both will be the same type of connection - cable 1.5mbit down 128kb down - thats the best i can afford in my country - israel. The reason i want 2 connections is cause i want to have one dedicated for massive 24-7 transfers i ussually do - *wink* *wink* , and another for regular browsing the web, online gaming, etc. at the moment i have 2 computers. what i want to know is if i can have one computer use both connections at the same time but not as in 1.5mbit + 1.5bit = 3mbit, but as at the same time i use my computer with connection A for file transfers i can also use my computer with connection B for browsing. i hope i made my question clear :-/ .

btw,
this is a longshot, but is there a way i can maybe get 3mbit from those two connections? from what i understand i get with my connection a router that gives 3 seperate IPs in case i need them for 3 computers in the house.

It is possible to make a sort of a 3mb connection out of that but it would require some expensive cisco equipment to do the load balancing.
It is also possible to give both computers access to different connections but it may require some other equipment for it to work right. Lets see if I can make a picture of this:

Internet1--router1--\
...........................Switch/Hub--Computers
Internet2--router2--/

Make router1 be 192.168.0.1 and router2 be 192.168.0.2. If you set the default gateway on your machine to 192.168.0.1 programs that need internet access (games,p2p, etc) will use internet1. Then, if you make router2 a proxy server and put that proxy info in you web browser all internet surfing (and downloads from browser) will go through internet2.
Well... there is my complicated way of doing it

I think the smallest router that would do it would be a cisco 2600 series router. The router itself is over $1000 dollars and you would need to get 2 ethernet modules for it that might tack on almost another $1000. Unless you are very desperate I don't think it is worth the money.

The diagram I made could use almost any router. You can get regular home routers for really really cheap. I think you can pick up a couple linksys routers for about $40-$50 each. Just make sure at least one of them can run a proxy.

I hate adding another option to confuse things furthur but I just became aware of a more cost effective way of load balancing those connections(making it a 3mb connection). If you can get your hands on an old compter, a bunch of network cards, and are willing to learn some linux you can make a load balancing router. I'm not much of a linux guru so I would have no idea where to start but I'm sure there are detailed insturctions out there on how to do it. Try the forums for some of the free router distros like IPCOP or ClarkConnect.
