multiple-instances

I have 3 instances of SQL Server 2008, each on different machines with multiple databases on each instance. I have 2 separate LUNS on my SAN for MDF and LDF files. The NDX and TempDB files run on the local drive on each machine. Is it O.K. for the 3 instances to share a same volume for the data files and another volume for the log files?

I don't have thin provisioning on the SAN so I would like to not constaint disk space creating multiple volumes because I was adviced that I should create a volume (drive letter) for each instance, if not for each database. I am aware that I should split my logs and data files at least. No instance would share the actual database files, just the space on drive.

Any help is appretiated.
