Does anyone know of a resource with a list of known products that use
LSP technology? Looks like most of the personal firewalls are at the
driver level as they should be but I can’t really think of anything else
that would be a LSP.
Thanks
Drivers for hardware implementations of TCP/IP are also such.

Lots of firewalls use TDI hooks or IM drivers (or both). Lots of
spyware-like programs use LSPs. LSPs are difficult, to say the least,
because of the installation mess. Layering order is not defined, and a
3rd-party product with a broken installer can break your product too. I
heard a bit of anecdotal evidence on another list saying that a
company’s support department got a call a week for a totally broken
winsock implementation.
LSPs were a good idea, but in practice, they’re like IM drivers on 98…
technically possible but loaded with practical difficulties.
