Top-level namespace question

[Rutger Vos]

Dear fellow authors,

I am planning to submit a new module to CPAN. The intended audience 
consists of evolutionary biologists, who may find the module useful
for parsing, analyzing and manipulating phylogenetic trees. The working 
title / temporary namespace has been Phylo::, but I gather there is some 
resistance to introducing new top-level namespaces. I have been trying 
to find out whether I can use Bio::Phylo, but the BioPerl mailing list 
has turned out to be quiet on the issue (I mean, I asked, waited, no-one 
responded). Perhaps someone here knows whether I can use Bio:: without 
being a contributor to the open bioinformatics foundation?

Thanks,

Rutger
