have multiple Option USB modems in one computer?

Hi guys! Im building an application where I want to be able to have 3 USB UMTS modems in one computer.

Does anyone have experience in using several modems at the same time?
I also want them to be able to be up and runninng at the same time,each connected to a different network through VPN tunnels.

So far, I have connected two Option Globetrotter Mini PCI Express cards with USB cradles (this is the option embedded development kit)
But I can use any modem, I also have two Option Globesurfer ICON that I can try If I need to, and I have PCCARD Globetrotters aswell.

If I have two USB modems they register as two seperate devices, the first getting usbtty0 to 3 and the second usbtty4-7

I use OpenSuse 10.3

do you think that will be any problems in calling with two or three modems at the same time?

Do I need to use PPP dial or can I get them to turn up like network interfaces so I can see them in IFCONFIG?

Thankfull for any advice

You probably need to use ppp to bring each one up, after which you will get a device like ppp0 which can be managed via ifconfig.
