Actually CDP was more or less made into a standard
It is LLDP-MED
http://en.wikipedia.org/wiki/LLDP-MED
If I remember correctly the new version of cisco phones support this. SO in other words you could use HP switches at the edge and Cisco in the middle and still have separate Voice and Data VLANS and no one is non the wiser (except the accountants paying the bills)

Well it's not that we want to get around CDP. We've done a good job of
staying "industry standard" where possible, and if there's a standard for
this we'd prefer to use it.
Personally speaking I'd prefer to license CDP now, and deal with a standard
later simply because CDP also helps set QoS parameters nicely.

802.3af is the inline power standard...that might be one way, but not sure
how.
802.1x is more likely the solution, which authenticates a user and allows
them on a particular VLAN.
That would be a novel way around CDP.
