Who, in addition to SprintLink, is currently implementing IP 
filtering based on CIDR block size (/19)?  And where can I go 
to learn more about this issue?

I've read the "Q&A conducted by Christy Hudgins-Bonafield with 
Alecia Cooper, group manager SprintLink product management." at
http://techweb.cmp.com/nc/online/sprint.html  but couldn't seem
to find much on what other carriers are doing.

Thanks.

AGIS published their route filter criteria:

Essentially, they will filter on /19 in the 206+.

They will filter on /24 for the 192-205 range.

Everything else (0-191) will be filtered in the /16.
