The question is what do you want to use PPTP to do? If you want to use it
to offer VPN business services, you should think again. All the layer 2
tunneling protocols are (by their own drafts' admission) not secure enough
on their own. IPSec protocols are they way you want to go for sure. If
you want to learn a bit more on this topic, check out:

The graphics are unreadable (due to the low-res versions Network World gave
us), but the text is at least a good starter on the topic of VPN security.
There are two articles there.

I'm interested to know what you have in mind specifically. Feel free to
email me privately. Thanks.
