We have around 200 students doing initial programming courses each submitting 5 programming assignments (a few hundred lines of code each) over the course of 2 semesters. In the last two years plagarism has become a major problem. Generally the attempts to disguise the copying are not very sophisticated and rarely go beyond altering comments and identifiers and changing the order of declarations. Occasionally a "pick and mix" strategy is used where students copy subprograms selected randomly from several different sources. This is typical in exercises of the form: given a package spec. for an ADT xxxx, write and test a suitable package body.
