I wouldn't be too quick to jump to that conclusion. There are many
vendors that have been marketing trading subscription services for
years, not to mention print media doing the same (albeit at a greater
delay).
And, if web site hosting services can be believed, any website can be
made fault tolerant with 99%+ uptime.
As for licensing, the most common approaches that I've seen for limited
life access are:
1. Expiring key file.
2. Username/password access to on-line content.
3. Automated nightly email receipt.
Given that you are talking about a local DLL (i.e. a file on the user's
disk), a key file to go with it sounds like a reasonable match. It also
has the benifit of not requiring a network connection. Though, it might
get pretty irritating to have to update a keyfile on a monthly basis.
Perhaps quarterly or semi annually instead.
Does anyone know of an open source keyfile generation utility?
