Managing ID files is the most painful problem with users who just use Notes client from time to time for a legacy application. The ID file in the vault may be expired, or pwd expired, or pwd not unique, and so one. The vault may not be accessible through pass-thru.
I hope that Nomad will be the solution, and be like a Verse or Sametime app, easy to configure with internet credentials, ready to play. The same could be said with HCAA though.
I understand the security and technical issues of the suggestion, but why not ? People do use iNotes over web only, and have the ID file embedded if needed. The same for Traveler.
The dream of having a beautifying legacy apps client without work, and with internet access straightforward.. :)
