I'd still like to see research into the "one huge .elc file" method, for the obvious benefits you listed. As far as I understand, the only difference between the portable dumper, and one-huge-.elc, is efficiency. Given infinite resources, the .elc method is much to be preferred, since everything we need "falls out" from existing design. I wonder what it would take to bridge that efficiency gap, or am I missing some new feature provided by the portable dumper? -- John Wiegley GPG fingerprint = 4710 CF98 AF9B 327B B80F http://newartisans.com 60E1 46C4 BD1A 7AC1 4BA2
