Would you consider paying, say, 2 or 3 dollars a month for a service that attempts to aggregate and curate almost all the 0 day mentions it can, alerting you when a particular keyword matches? Something like a targeted Google Alert? I presume obscure pieces of software should be dealt with in a case-by-case basis. There must be a service that does this, I can't find any at the moment. If you're allowed to say, how rare is the software you want to track? This has piqued my interest because I've been in the same situation and it became a hassle to manage many mailing lists. My solution never went beyond a few mail filters. Nowadays, Google Alert helps quite a bit but it is hard to keep the noise out. I'm certainly no tptacek, but I'd be most willing to give it a shot!
