At Indiana we require VPN for all non-guest wireless use. We use 3030's with native clients. It's been serviceable but not perfect. I heard similar complaints from Mac users, but not the level of "this always happens when I move files".
We never resolved the issue and have now moved to Cisco's ASA which seems to work much better for Macs. I stayed connected for 24 hours over a wired connection last week. A note on the ASA: It costs less than a 3030, does L2TP in hardware. We hit 850 L2TP users yesterday with 20% CPU utilitzation. The platform does not support PPTP, which is fine with us. We'll keep a couple of 3030's around for that purpose but we're trying to get everyone moved to L2TP. It's still the first week of the semester so we'll see how it holds up over the next few weeks.
