Re: An idea: GxSE

[Brian E Carpenter <brian@hursley.ibm.com>]

Another couple of points:

1. Somebody asked how to allocate the SK prefix. This is easy enough to
do in several ways, but a painless way is to use the site's RFC 3056
prefix, at least for the first ten years or so of allocations. 

2. Paul says that sites would have to renumber when they merge. I'm not
convinced that is a requirement. If two sites with different SK prefixes
merge, it seems to me they can simply route between those two prefixes
internally. Even if renumbering turns out to be a good idea in the long
term, it can be done piecewise - no flag day needed.

Apart from that I am worried about the amount of complexity you are asking
hosts to implement. For some types of host (e.g. handhelds) this will be an
issue. I think there could be a simplified version of GxSE lurking in there
somewhere.
