superb report - of course i agree with all of it except that it could
be a bit more global/international (i udnerstand that the NSF Is a US
agency but) - for example, the successes of the ARPANET, DARTNET and
other testbeds included international collaboration (AND
infrastructure) as does the Internet II program (even broader, though
its more an application testbed outside the US, not strictly in the
spirit of this report - it IS however a network of networks!)

the recommednation on unlicensed testbed spectrum is especially
welcome but last time i checked,
the FCC doesnt have any jurisdiction outside the US where there's more
wireless (last time i looked) but more daft regulation, so it might be
nice if someone could find the right heads to bang together in the EU
(and i guess asia/pacific, though as far as i can see, with docomo and
other stugff, they have their act together there already) and i guess
south america (scuse my compelte lack of knowledge of wireless there -
i assume they use satellites a lot due to demographics and distance!)

so great stuff, but how do we up the ante?
