I came across a post in 2005 (Thomlinson/RB Smissaert) that suggested have a
loader add-in on the workstation that opened the add-in on a shared drive not
as add-in but as a normal but hidden xls file. There was some suggestion that
excel couldn't handle add-ins remote from the host but I have not tested this.

My question though is if a pseudo xla or a genuine referenced xla on the
shared drive is already open will a second user be greeted by the 'File is in
use/Read only/Cancel/Notify' dialog?
