 impact to researchers/companies

agree, the vanity hunting is going to be there but I suppose as with any
bug ID that is going to happen.
But beyond that I don't think it matters as much. In the end of the day if
somebody can use OVI or OVE to identify their bug then at least we got some
level of reference to look it up on google.

I was toying with 4digit IDs that would be random enough, thats a
possiblity too, the only problem is that there is a overhead of doing DB
sorting and lookups to make sure their don't clash. Thats why ovi uses
sequential numbers - its just easier to manage.

Cheers,
