[Serusers] Re: SER database sharing

[Greger V. Teigre]

Hi Andreas,
Don't take me wrong. Your setup sounds very robust and well thought-out 
to me.  I just pointed out that for small-scale setups (like an SMB or 
enterprise installation), one might want to find a setup involing fewer 
components and thus reduce the number of areas competence is required.
Also, my reference to "makes sense for some setups" is not an 
evaluation, more a reflection over all the various setups people have 
opted for.
    SER/openSER, in my experience, for most users the problem is not 
lack of features, but quite the opposite... so some simplications in the 
form of best practice setups would do good. Just like the onsip.org configs.
