I am pretty sure it is NOT a good idea.

One of the things which is becoming apparent to a number
of service providers is that that a low RTT is necessary
but insufficient for "user happiness" - RTT _stability_ is
often more important.

Regrettably, there is little to no way for an end system
to understand the short term stability of a path other than
by trying to move traffic across it.

Why not?  It should be an explicit goal of the next cut
at an IPng, and shouldn't just stop at SOHO -- it should
go right to individual homes, _at least_.  I have multiple sets of
wires coming into my flat, and live in a regulatory environment
where each of those wires (and some new ones) is allowed to carry
data/POTS/ISDN/cabletv/you-name-it.

And then there's Sweden, which is several steps ahead.

Yes, they really are serious about more than a quarter of a million
homes which will have the moment-to-moment chance to use
any or all of: FTTC/FTTB/FTTH from these folks, cable modems,
or the various offerings from the various telcos (xDSL, dialup)
for Internet connectivity.

The days when only a handful of middle-aged Swedish women have broadband
connections like this: http://www.stupi.se/Bilder/7296-3251-0759/g.html
into their apartments are numbered.  (BTW, if you look closely, you'll
see her apartment's network was multihomed already.)

The assumption that only larger organizations will want multihoming
and at-will-provider-changing is a bad one.
