For closed archives I guess it's easier, as you can prescribe whatever 
identifier system you like, no matter how exotic. But if you are going to 
archive public data from many many sources, I imagine you want to go with 
the greatest common denominator, which is HTTP URIs for the Semantic Web.

Creating some recommendations for better HTTP URIs is likely to be more 
productive, in the end, than trying to get people to adopt some new scheme.

Also: If you are building some grand life sciences archive with the goal of 
archiving all public life sciences data that is available, does it really 
help if a few of the databases support the LSID or DOI or whatnot system?

Don't quite follow the last part of your argument (we should recommend that 
resources from the Semantic Web are not archived for long?), but you're 
right that what we are talking about is identifiers for the Semantic Web, 
and recommendations is something that this group could produce, I hope.
