I have been in talks with a prospective client about writing an application. Its a simple CRUD application, with a requirement that it needs to go offline (the client's business is a mobile one, and one that involves auditing equipment. They occasionally find themselves in underground basements or buildings that may potentially block off internet access).
I have considered several options the two primary ones being Gears On Rails [http://code.google.com/p/gearsonrails/] or Adobe AIR.
I was wondering if anyone here has had any experience writing such applications, and if there was any advice to be given. I am open to considerations for other technologies, but I am not sure what those would be.
I will admit, I am not sure if this is a question for HN, but I hope it is.
Many thanks in advance.
