Anonymous proxies & ITAR question

[Background] I wanted to grab a copy of the 128 bit version of MSIE, but my ISP hasn't enabled reverse DNS lookup, so I decided to try running through an anonymous proxy server to scoop it and lo-and-behold, aside from being brutally slow, it worked like a charm. I may have the opportunity in the near future to set up a proxy server, but this concerns me... Under ITAR regs, if a "foreign national" was to use the server to get access to "munitions" (sure, software kills, didn't cha know?), could I be held in violation? Even if all they had was circumstantial evidence, I'd really like to avoid being indicted - puts a real kink in one's social schedule. Your thoughts on this would be appreciated.
