Equipment Bond for Software?

[vicky_molokh]

Greetings, all!

For many skills, 'equipment' is actually software, be it a programme for brain hacking, a word processor, or the expert system that gives advice on precision aiming. But where things get complicated is where a piece of software counts as 'mine'. Well, sure, things are crystal clear when the software was written by the character in question for oneself only. But this isn't a requirement for equipment bonds, so I wonder what counts as sufficiently individualised for purposes of equipment bonds when not writing one's own software.

Obviously brand-and-model can't be arbitrarily changed, just like with non-informational tools. Upgrading equipment doesn't interfere with Equipment bond, so apparently version increments are okay. But then what counts as required personalisation? UI customisation, relevant macros, databases and templates? That seems right for things like a spreadsheet programme, but not so much for a minimalistic editor with a same-on-all-computers philosophy such as ed or vi.

Thoughts?
Thanks in advance!
