Extra "non-vex" sensors

[MRClark]

i was at radioshack the other day, and found that the have 2axis accelerometers (http://www.hobbyengineering.com/H1581.html) and i figured it was something that would be cool to use on my vex. however, one of my friends explaned to me that the way that it would plug in would be into an analog input, but the vex does not have one.... so my questions are:
1) is he right?
2) is there any way to connect it to the vex system?
3) how?
4) if not, are there any accelerometers that are vex compatible?
5) how would i program it in easyc?

Thanks for your help
