Sure, regarding those 4 questions:
1) is it possible to order your ready made hardware with preinstalled PLUTO systems here in Europe?
Yes. Our strongest manufacturing partner in Europe, Digital Logic, based in Switzerland, already has units ready to ship. They are awesome boxes--very high-end, though. If you want something lower cost, we can set you up with another manufacturer. However, they are just standard Servers and Media PC's, so you could use name brand suppliers like HP, Dell, etc. as well.
2) Media Directors look like the most interesting equipment, because as we understand we can use almost any server platform powerfull enough for building Cores. Is it possible to buy/order your MD devices separately, maybe as barebones (no HDD, RAM, processor)?
We don't make or sell any hardware. We're like Windows. We provide the software platform to hardware manufacturers and they pre-install it. So it's up to the h/w mfg to say what configurations they support. Or we can provide the software directly to you.
3) is it possible for us to build our own installations, using locally bought hardware (server systems for Pluto Core, MSI or ABIT barebones as Media Directors, etc) and provide it to our customers for some configuration and support fees? We don't want to brand those systems as ours, we are ready to supply customers with all the required info about PLUTO HOME as well as with your original software and installation sources. Does it requie any licensing from you?
Yes, it's possible. The core libraries and modules are GPL. A license is never required--we provide them totally free. The modules that are specific to our smarthome/media server sector are offered under the Pluto license. That allows you to do whatever you want with the software for free, without paying a license, just like GPL, unless you will be distributing it with hard goods (ie offering a turnkey solution). It sounds like you will be offering a turnkey solution, so a license is required. However our license fees are not a lot.
Go to plutohome.com/support, click 'about', 'licensing'. It's all explained there, including the full text of the licenses.
4) if at least one of the options above is true, do you have some other advertising material (both in printed or electronical form) so we can translate it to our local languages? We can also provide you with a mirroring site here, doing all required translations.
We do have some brochures and flyers, although 99% of our marketing exposure is through the web site. We could discuss mirroring/translation options. I don't know what's involved--not my specialty.
