Colin/Magnus/Steve,

I've got two questions regarding the following snippet from the re-charter:

"The group continues to be precluded from work on codecs themselves
because of overlap with the other standards bodies, and because the
IETF does not have the ability to effectively review new codecs. An
exception was made for the freeware iLBC codec on a highly experimental
basis, but acceptance of new codec work is unexpected and subject
to rechartering."

1) With regard to iLBC, while I understood that the issue was not fully
resolved, I thought AVT was to be the "primary repository" for iLBC's
definition (that is, not the ITU-T or other standards defining bodies).
I more or less understand what "experimental" means in the IETF - but
what does "highly experimental" mean? Is it even less probable that
iLBC will eventually attain standards status by the additional adjective?

2) With regard to RGL (for people unfamiliar to RGL, see www.vovida.org
for details), RGL is really a "lossless data compression technique" applied
to (A or mu-law) G.711. Steve had requested that "avt" be included in the
titles of RGL revisions - so I assumed it was a working group item. Is RGL
covered in the "re-chartering statement" (above)? Or is RGL, by virtue
of it having more in common with a data compression algorithm than a
(lossy) signal processing codec, exempt (no codec expertise needed - a
rational noted above)? If this is unclear, could you obtain further guidance
from the ADs (Allison) or the IESG?

Thanks,

Michael Ramalho
