There's a lot of interest in cloud-based synchronisation and sharing services, as witnessed by the number of people using Dropbox, SugarSync and others.

LogMeIn put its Cubby service into beta last April.

Among the key features of Cubby are the ability to sync or share an arbitrary number of folders, and provision for DirectSync Cubbies that synchronise on a peer-to-peer basis without going through LogMeIn's servers.

Now the service has gone live, LogMeIn is differentiating the free and paid versions of Cubby.

Cubby Pro (starting at US$6.99 per month per user if prepaid annually) comes with 100GB per user (pooled across users on the same subscription), allows the use of DirectSync Cubbies, and provides greater access controls.

A 14-day free trial of Cubby Pro is available.

"Cloud file sharing services too often force people to make choices between personal or business use, simplicity or flexibility, accessibility or security - compromises that don't reflect the realities of how technology is increasingly adopted and used in today's mobile workplace," said LogMeIn CEO Michael Simon.

"A nod to the rise of employee-introduced consumer cloud apps, Cubby is designed to deliver the elegance and ease individuals enjoy with the security and flexibility businesses demand.

"We believe that the overwhelmingly positive response we received during the Cubby beta - attracting both first-time cloud file sharing users and converts - points to broader demand for services like Cubby that help individuals and businesses alike reimagine the ways they collaborate on content."
