WiFi security implications

["Tres London" <telconstar99 () wblondon com>]

Hello List, 1st time poster here :)

If I work for a financial firm, have a laptop with wireless access and
am at a publicly available wireless access point, and want access to my
network via VPN, what are the security implications?

My company currently allows people from home to VPN into the network at
work, but IT is nervous about allowing it over a wireless connection
because of security implications. 

My point is that VPN should be secure enough on it's own, even if people
access my information, it's still encrypted with IPSec (or something
like that).

Thoughts?

Thanks,
