There is two problems with the above sugggestion of using
dcmqrscp as real-world, in production DICOM server.

Quote from the documentation:

	The DCMTK dcmqrscp application implements a DICOM image
	storage/query/retrieve SCP which has been designed primarily as an
	independent framework for cooperative tests and demonstrations of
	DICOM connectivity by medical imaging vendors.
	...
	It is important to note that dcmqrscp is
	primarily intended to be used as a demonstration server rather than a
	real "PACS replacement". Scalability is quite limited, both in terms
	of number of images/studies and in number of parallel clients.

And, indeed, there's a non-optional Quota setting:

	# Each row of the AETable defines an Application Entities (AE) Title known
	# to the dcmqrdb application.  Each AE Title represents a separate
	# image database located in the specified file system directory (storage area).
	# Each AE Title has read/write, quota and peer access restrictions.
	#
	# Entry Format: AETitle  StorageArea  Access  Quota  Peers
	# AccessFormat: R | RW | W
	# Quota Format: ( maxStudies, maxBytesPerStudy )

including a hardcoded upper limit:

	http://forum.dcmtk.org/viewtopic.php?f=1&t=1620&view=previous

Quotas all fine and well but here's what dcmqrscp DOES on
exceeding the quota (from the man page):

	The dcmqrscp application is intended to be used in DICOM
	demonstrations and as a compatibilitiy test tool. In
	particular, dcmqrscp WILL DELETE IMAGES if its quota
	restrictions have been exceeded.

I don't understand how this can be suggested as
a serious answer to my inquiry.
