Hi,

I just want to point out that RADEXT is doing somewhat similar solution 
for a specific use case when shuffling around large chunks of 
authorization data. See 
http://tools.ietf.org/html/draft-ietf-radext-radius-fragmentation-06

RADIUS' problem is the statement in the original specs to limit the 
packet size to 4K although the packet encoding would allow 64K packets. 
The above I-D is a "hack" to be compatible with deployed proxies etc 
that pedantically follow the 4K rule.
