[collectd] Changing and "non-standard" OIDs

I'm evaluationg how to best monitor a Cisco AP.

Here is the results of snmpwalking the cDot11ClientCurrentTxRateSet
OID for 3 SSIDs:

= STRING: "l"
= STRING: "l"
= STRING: "l"

One of the things I want to monitor is the clients data rate, given in
the OID SNMPv2-SMI::enterprises.
Followed by some numbers I take are random to each AP.
Followed either by a missing number for the first SSID configured and
then by 50 for the second, 51 for third configured SSID and so on.
Then followed by the client mac-address encoded octally or something.

1. I want to collect the number of clients using a given data-rate at
the current moment, for each SSID.
2. I may also want to collect the data-rates for each client over time.

Is this possible with collectd, and how easily if so?

I'd rather not have to go to my boss and tell him I spent N hours to
figure out it's not possible or that is too hard for me to do on my
own :)

Cheers and TIA
