Jesus Climent asks for a "client/server solution for my bookmarks", which I read as "del.icio.us clone". As the comment feature is not available on his blog, I answer with another blog post.
I know of the following Free Software del.icio.us clones:
- Scuttle (PHP, GPL)
- Rubric (Perl, Artistic license + GPL)
- Insipid (Perl, GPL)
I haven't tested recent versions of any of those, but I'll give scuttle another try soon, as I have wanted my own local del.icio.us for quite a while...
