Can't really merge them. Even having two different ISP lines, and if the PC has Dual Nic's and one is plugged into it it doesn't "Double" your speed. It will only use one or the other. Only time dual nic's are good are for servers where you can do what they call Nic Teaming and what it does is balance the load going to the server. You could technically do the same with the lan but 1) Very few nic cards do that and the ones that do you only really find on server boards and 2) I don't know how that would really work since each one would be trying to give out an IP address to the server on different subnets. Just won't work. Your better off keeping one connection but double the speed.
Had a client where their previous IT guy said "Hey get two fios lines! it will double your speed! Uhhh YOU CANT DO THAT IDIOT. They cancled the one line and doubled the speed on one.
The only reason why most people would have dual nics and use them or have the need for two networks if is the PC's need to stay seperate but they have a comon server or something. But yea just in simple terms can't be done.

You can get a dual wan router and it will sorta use both. You can also do it by manually putting route statements in the PCs.
What you in effect do is access some sites out one ISP and other outs the second. It tends to get very complex because many sites are made up of multiple IP blocks and if you get part on one ISP and part on the other the site will detect it as a attack.
The key problem you have is not so much combining the ISP lines it is you have 2 different ip addresses. You can't have 2 ip acting as a single machine it completely violates the principles the internet is built on.
Although it is technically possible to combine the lines using a layer 2 protocol the ISP would have to do this for you since you would need equipment on both ends. It is seldom a cost effective choice
