There are a huge number of issues open for import/export of file formats 
for other applications. I think it would be safe to assume that everyone 
would rather have their passwords kept in sync with their desktop 
application, rather than simply importing them and letting them diverge 
over time.

Fortunately, Secrets could solve both problems at the same time. If 
Secrets created an OpenSync (http://www.opensync.org) conduit to convert 
Secrets files to/from a generic XML format, it would allow synchronisation 
of Secrets files with other Secrets files (over a number of transport 
options, such as USB, Bluetooth, WiFi). Secrets developers could then 
create conduits to convert the most important formats to/from the XML 
format. This would allow these formats to synchronise with other files in 
that format, or with the Secrets format, or any other formats that have a 
conduit.

This approach may be slightly more work for the first format or two, but 
would have the epic advantage that it makes it increasingly attractive for 
other projects to write a converter to/from the XML format (perhaps to get 
support for KeePass), which would give Secrets that ability as well.
